SPECIFICATION forming part of Letters Patent N o. 711,491, dated October21, 1902. nppiipptionineaepriie,1902. spannt. 102.113. (Nomad.)

T0 all whom, it may concern:

Be it known that I, BENJAMIN FRANKLIN GRANDSTAEF, a citizen of theUnited States, and a resident of Peru, in the county of Miami and Stateof Indiana, have made a certain new and useful Invention in Weather-Strips; and I declare 'the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it appertains to make and use the invention, reference beinghad to the accompanying drawings, and to letters of reference markedthereon, which form a part of thisr specification.

Figure l is a section on the line 1 1, Fig. 2, showing the invention asapplied with the weather-strip in lowered position. Fig. 2 is a frontelevation of the invention as applied, parts being broken away. Fig. 3is a section on the line 3 3, Fig. 2, with the weather-strip in raisedposition. Fig. 4p is a detail perspective view of the strip proper. Fig.5 is a detail View of the guide-block s'.

The invention has relation to weatherstrips for the bottoms of doors;and it consists in the novel construction and combinations of parts, ashereinafter set forth.

In the accompanying drawings the letter a designates a door, b b thedoor-jambe at the sides, and c the sill or carpet-strip at the bottom ofthe doorway.

e. is the weather-strip, which is designed 'to extend under the bottomof the door. It is made of metal and is formed with upturned end flangesf, connected at their inner ends with an upturned back ange g, which eX-tends farther upward than the tops of the Y end flanges, this extensionh being perforated at 7s la for the passage of the hinge-pins ZZ and atm for the attachment of the platespring n to the door.

p p indicate plates or castings, each of which is perforated through itsupper and vertical portions for the reception of screws' the lug orfiange r and the face of the door is an angular interval, which allowsplay to the back flange of the weather-strip.

.The lifting-spring fn is normally bent at its middle port-ion and isriveted to the middle of the weather-strip flange in such wise that itsupper portion or tongue projects upward above the liange and engages awear-plate w, which is let into the bottom of the face of the door. Thisspring n serves normally to hold lthe weather-strip u p, so that it willclear the carpet in passing over the same when the Vdoor is opened.

Near the inner end or hinge side of the sillstrip c is provided abeveled wear-plate c, which serves to raise the weather-,strip in apositive manner when the doorl is being openedv or closed tothe properheight to 'pass over the sill-strip without striking the same.

At the bottom of the inner or khinge jamb of the doorway is secured aguide-block s, the -inner end of which is formed with an obliquedownward bevel on its under side, as indicated at if, the i beveled endserving to engage the free edge of the Weather-strip at its inner-endportion and force such edge down into close engagement' with the sill.

At the bottom of the outer jamb of the doorway is secured a bevel-endguide-block s,which when the door is closed engages the edgeof theweatherfstrip at its outer end portion and serves also to force its freeedge down to close engagement with the sill.

In this wise it is designed to provide a closely-engaging weather-stripwhich when the door is yclosed will not only be securely pressed againstthe sill, but also will be tightly pressedby its back flange against thebottom of the inner door-face, and its ends being flanged will cover inthe ends of the bottom of the door, thus preventing entrance of Water atthe ends of the strip and serving as stiffening-ribs.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

l. The combination with a door and the sill of the doorway, of a hingedweather-strip having the upturned back ange provided with perforationsfor the hinge-pins, the wearplate upon the door and the plate-springsecured to the back iiange' and bearing at its upper end upon' saidwear-plate, substantially as specified.

2. The combination with a door, of the IOO Weather-strip having endflanges and an eX- tended back lange, the door-plates having inclinedflanges or lugs forming angular intervals between themselves and theface of the door, the hinge-pins passing through said lugs andWeather-strip, the Wear-plate in the door, and the plate-springconnected to the middle of the Weather-strip and engaging saidWear-plate, substantially as specified.

A Weathestrip of metal, having the uptnrned end anges, and the npturnedback flange conneoted to said end flanges, the upu ward extension ofsaid back flange perforated forthe hinge-pins, and the bent springsecured to the middle of said back flange, substantally as specified.

In testimony whereof I allx my signature in presence of two Witnesses.

BENJAMIN FRANKLIN GRANDSTAFF. Witnesses:
